It is assumed that converting cropland-pasture to cropland (either for producing traditional crop or dedicated energy crops) does not cause land use emissions. It is assumed that converting cropland-pasture to cropland (either for producing traditional crop or dedicated energy crops) causes land use emissions. Based on EFs obtained from the Woods Hole data set. Based on CARB EFs. Based on the TEM EFs obtained for the base case assumption.
